* * @tile_height: %gint for tile size
|
|
* * @pyramid: set %TRUE to write an image pyramid
|
|
* * @squash: set %TRUE to squash 8-bit images down to 1 bit
|
|
* * @miniswhite: set %TRUE to write 1-bit images as MINISWHITE
|
|
* * @resunit: #VipsForeignTiffResunit for resolution unit
|
|
* * @xres: %gdouble horizontal resolution in pixels/mm
|
|
* * @yres: %gdouble vertical resolution in pixels/mm
|
|
* * @bigtiff: set %TRUE to write a BigTiff file
|
|
* * @properties: set %TRUE to write an IMAGEDESCRIPTION tag
|
|
* * @strip: set %TRUE to block metadata save
|
|
*
|
|
* Write a VIPS image to a file as TIFF.
|
|
*
|
|
* If @in has the #VIPS_META_PAGE_HEIGHT metadata item, this is assumed to be a
|
|
* "toilet roll" image. It will be
|
|
* written as series of pages, each #VIPS_META_PAGE_HEIGHT pixels high.
|
|
*
|
|
* Use @compression to set the tiff compression. Currently jpeg, packbits,
|
|
* fax4, lzw, none and deflate are supported. The default is no compression.
|
|
* JPEG compression is a good lossy compressor for photographs, packbits is
|
|
* good for 1-bit images, and deflate is the best lossless compression TIFF
|
|
* can do.
|
|
*
|
|
* Use @Q to set the JPEG compression factor. Default 75.
|
|
*
|
|
* Use @predictor to set the predictor for lzw and deflate compression.
|
|
*
|
|
* Predictor is not set by default. There are three predictor values recognised
|
|
* at the moment (2007, July): 1 is no prediction, 2 is a horizontal
|
|
* differencing and 3 is a floating point predictor. Refer to the libtiff
|
|
* specifications for further discussion of various predictors. In short,
|
|
* predictor helps to better compress image, especially in case of digital
|
|
* photos or scanned images and bit depths > 8. Try it to find whether it
|
|
* works for your images.
|
|
*
|
|
* Use @profile to give the filename of a profile to be embedded in the TIFF.
|
|
* This does not affect the pixels which are written, just the way
|
|
* they are tagged. You can use the special string "none" to mean
|
|
* "don't attach a profile".
|
|
*
|
|
* If no profile is specified and the VIPS header
|
|
* contains an ICC profile named #VIPS_META_ICC_NAME, the
|
|
* profile from the VIPS header will be attached.
|
|
*
|
|
* Set @tile to TRUE to write a tiled tiff. By default tiff are written in
|
|
* strips. Use @tile_width and @tile_height to set the tile size. The defaiult
|
|
* is 128 by 128.
|
|
*
|
|
* Set @pyramid to write the image as a set of images, one per page, of
|
|
* decreasing size.
|
|
*
|
|
* Set @squash to make 8-bit uchar images write as 1-bit TIFFs. Values >128
|
|
* are written as white, values <=128 as black. Normally vips will write
|
|
* MINISBLACK TIFFs where black is a 0 bit, but if you set @miniswhite, it
|
|
* will use 0 for a white bit. Many pre-press applications only work with
|
|
* images which use this sense. @miniswhite only affects one-bit images, it
|
|
* does nothing for greyscale images.
|
|
*
|
|
* Use @resunit to override the default resolution unit.
|
|
* The default
|
|
* resolution unit is taken from the header field
|
|
* #VIPS_META_RESOLUTION_UNIT. If this field is not set, then
|
|
* VIPS defaults to cm.
|
|
*
|
|
* Use @xres and @yres to override the default horizontal and vertical
|
|
* resolutions. By default these values are taken from the VIPS image header.
|
|
* libvips resolution is always in pixels per millimetre.
|
|
*
|
|
* Set @bigtiff to attempt to write a bigtiff.
|
|
* Bigtiff is a variant of the TIFF
|
|
* format that allows more than 4GB in a file.
|
|
*
|
|
* Set @properties to write all vips metadata to the IMAGEDESCRIPTION tag as
|
|
* xml. If @properties is not set, the value of #VIPS_META_IMAGEDESCRIPTION is
|
|
* used instead.
|
|
*
|
|
* The value of #VIPS_META_XMP_NAME is written to
|
|
* the XMP tag. #VIPS_META_ORIENTATION (if set) is used to set the value of
|
|
* the orientation
|
|
* tag. #VIPS_META_IPCT (if set) is used to set the value of the IPCT tag.
|
|
* #VIPS_META_PHOTOSHOP_NAME (if set) is used to set the value of the PHOTOSHOP
|
|
* tag.
